Bell Medium Strake Kit

Just curious what the direct operating cost''s are for the operator, intial purchase and/or any saved maintaince costs, or has any one been running them long enough to track those costs. If so,are operators passing those cost''s onto the customer? I know Forestry regardless of province doesn''t. However, curious if skiing, drilling, and logging customers realize the DOC''s and are recoginizing this when bid''s come in? From a Drivers stand point flown both and still siitin on the fence.
